After listening to the administration talk recently I dont see any chance they take a G at 8.
IMO they are much more likely to take one of the three players listed or Barkley, who I think is #1 on their board, and they believe (openly stated it) that there are 2-3 franchise QB's in the draft, and they need one. Barkley IMO is an option at 8, and if they stayed pat at 42 would be the pick (nice pick) IMO, although I dont see them standing pat at 42 if they dont take a QB/or trade down from 8. I just dont see them taking the risk of missing out on a QB, which I believe will come in the first round one way or another (if you are projecting a trade and have them taking Barkley at 42 as a way of doing so, then I think you are money :) )
IMO Jones/Mingo/Austin at 8 and a trade up for Barkley is very realistic. I just dont see them taking a G at 8 at this point.
